The size diversity of the Pteridaceae family chloroplast genome is caused by overlong intergenic spacers [PDF]

open access: yesBMC Genomics
Background While the size of chloroplast genomes (cpDNAs) is often influenced by the expansion and contraction of inverted repeat regions and the enrichment of repeats, it is the intergenic spacers (IGSs) that appear to play a pivotal role in determining
